Next time your in a hotel try this.  Install iTunes.  Switch on the option to search for music libraries which I believe is on by default.  Listen to other peoples music.  You can do this without paying a penny since you're usually given an IP address to connect to the local network before you pay, you just aren't granted external privileges.

I found this out in my London hotel.  I connected to the wireless LAN, fired up iTunes and there they were!  Three other people's iTunes music libraries.  Of course, iTunes is designed to prevent you from stealing other people's music but I did wonder if the people concerned realized they were sharing their music for others to browse.  In one case, I was able to figure out the computers IP address and connect to their share list BAD BAD BAD security.  Interesting feature though.

Try it next time you're in a hotel or widely used public hotspot and see what you can find!  My limited experience so far is that most iTunes users have reasonable taste in music ... your mileage may vary.
